Background and Objective: Patient-reported outcomes and blinded observer rating scales are subjective and unreliable but are extensively utilized to evaluate cosmetic office-based treatments, including ablative lasers. This study aims to assess the practicality of using noninvasive and minimally invasive methods for objective skin assessment following a skin rejuvenation treatment. Study Design/Materials and Methods: Twelve patients received a single 1,470/2,940 nm laser treatment for facial rejuvenation. Assessments were performed before treatment, and 7 days, 3 weeks, and 3 months posttreatment. Images were taken with the VISIA Skin Analysis System to measure wrinkles, textures, pores, ultraviolet (UV) spots, brown spots, red areas, and porphyrins. Other non-invasive skin measurements-highresolution ultrasonography, optical coherence tomography, transepidermal water loss and BTC 2000-were used to measure epidermal/dermal thickness, blood flow, surface roughness, wrinkle depth, attenuation coefficient, elasticity, laxity, and viscoelasticity. Microbiopsies (0.33 mm in diameter or the equivalent of a 23-gauge needle) were collected for histology and gene expression of tissue rejuvenation. Results: Significant improvement in facial skin aesthetics after laser treatment was recorded in UV spots, brown spots and pores after 3 weeks and in UV spots and brown spots after 3 months. The dermal attenuation coefficient decreased significantly at 3 weeks, while blood flow 0.5 to 0.7 mm below the skin surface increased significantly between 5 days and 3 weeks following treatment. Epidermal hyaluronic acid expression assessed by immunostaining and expression of inflammatory genes were elevated at 7 days posttreatment compared with untreated or 3 months posttreatment. There were no statistically significant changes in collagen or elastin-related genes between groups at the studied parameters. Conclusion: Non-invasive devices can be effectively used to provide objective measurements of skin structure, pigmentation, blood flow, and elasticity to assess the efficacy of facial skin rejuvenation treatments. Furthermore, microbiopsies can objectively evaluate facial skin rejuvenation without scarring. Using non-invasive skin imaging, a single treatment with the 1,470/2,940 nm laser was observed to be effective in improving skin appearance after 3 months, namely in reducing UV spots and brown spots, without significant changes in the tissue at the molecular level, as assessed by microbiopsy.

Most medical schools in the United States have an associated student-run free clinic (SRFC) providing medical care to the underserved population around the campus. SRFCs provide students with opportunities to practice history-taking and diagnosis skills. There have been a few studies that have evaluated patient satisfaction within SRFCs; however, these studies report limited aspects of care within these clinics. This study hopes to determine the levels of satisfaction with clinical staff and operations and to ensure that the medical needs of patients are being met. Results showed that 91% of the patients were satisfied or very satisfied with their overall clinic experience. The highest scoring parameters were “courtesy/respect of staff”, “availability of free or affordable medications”, and “doctor’s knowledge”. Overall, the patients are satisfied with the staff, care, and availability of medicine provided by the Keeping Neighbors in Good Health Through Service (KNIGHTS) clinic. Most patients enjoy participating in the training and education of future physicians and would recommend this clinic to a friend or family member. The lowest satisfaction rates were associated with length of visit and wait time. In the future, SRFCs should work together to assess patient satisfaction in the clinics, identify problem areas, and develop generalizable interventions for improvement.

Background: Migraine surgery is an increasingly popular treatment option for migraine patients. The lesser occipital nerve is a common trigger point for headache abnormalities, but there is a paucity of research regarding the lesser occipital nerve and its intimate association with the spinal accessory nerve. Methods: Six cadaver necks were dissected. The lesser occipital, great auricular, and spinal accessory nerves were identified and systematically measured and recorded. These landmarks included the longitudinal axis (vertical line drawn in the posterior), the horizontal axis (defined as a line between the most anterosuperior points of the external auditory canals) and the earlobe. Mean distances and standard deviations were calculated to delineate the relationship between the spinal accessory, lesser occipital, and great auricular nerves. Results: The point of emergence of the spinal accessory nerve was determined to be 7.17 ± 1.15 cm lateral to the y axis and 7.77 ± 1.10 caudal to the x axis. The lesser occipital nerve emerges 7.5 ± 1.31 cm lateral to the y axis and 8.47 ± 1.11 cm caudal to the x axis. The great auricular nerve emerges 8.33 ± 1.31 cm lateral to the y axis and 9.4 ±1.07 cm caudal to the x axis. The decussation of the spinal accessory and the lesser occipital nerves was found to be 7.70 ± 1.16 cm caudal to the x axis and 7.17 ± 1.15 lateral to the y axis. Conclusion: Understanding the close relationship between the lesser occipital nerve and spinal accessory nerve in the posterior, lateral neck area is crucial for a safer approach to occipital migraine headaches, occipital neuralgia, and new daily persistent headaches and other reconstructive or cosmetic operations.
